                ASCII（American Standard Code for Information Interchange，美国信息互换标准代码，ASCⅡ）是基于拉丁字母的一套电脑编码系统。它主要用于显示现代英语和其他西欧语言。它是现今最通用的单字节编码系统，并等同于国际标准ISO/IEC 646。
            </p>
            <p>
                ASCII第一次以规范标准的型态发表是在1967年，最后一次更新则是在1986年，至今为止共定义了128个字符，其中33个字符无法显示（这是以现今操作系统为依归，但在DOS模式下可显示出一些诸如笑脸、扑克牌花式等8-bit符号），且这33个字符多数都已是陈废的控制字符，控制字符的用途主要是用来操控已经处理过的文字，在33个字符之外的是95个可显示的字符，包含用键盘敲下空白键所产生的空白字符也算1个可显示字符（显示为空白）。
